The female had two previous obstetric scans; one at 8+3 weeks of gestation reporting a fetus of crown rump length of 19.3 mm and second anomaly scan at 21+6 weeks of gestation reporting normal findings.
At 37+2 weeks of gestation the female presented to the emergency department in end stage of labor. On monitoring, persistent fetal tachycardia was noted with fetal heart rate of 180-187 bpm.

A 3.180 kg infant was delivered with Apgar score of 7/10 at 1 minute and 8/10 at 5 minutes. On examination of placenta, presence of a bilobed placenta with an accessory lobe connected to the main lobe of placenta by fetal blood vessels was confirmed.
